zipman: read -r protects against those evil manpages whose filenames contain backslash escapes, (muahahaha?) IFS= read protects against filenames with: - leading whitespace (but no one is actually stupid enough to configure their MAN_DIRS=() in makepkg.conf with such silly directories, *right*?) - trailing whitespace (but likewise, no one should be stupid enough to write an uncompressed manpage for section '1 ' or something) Also fix several other cases where we read filenames without protecting against surrounding whitespace, or without using null-delimited filenames when we could trivially do so.
